دانلود کتاب Learning jQuery

دوره آموزش JQuery

امروزه توسعه دهندگان در راستای اتوماسیون عملیات رایج و آسان سازی کارهای پیچیده و در نتیجه ساختن سایت های تعاملی و کارامد، به کتابخانه های زبان JavaScript نظیر jQuery روی می آورند. از آنجایی که غالب برنامه نویسان تحت وب تجربه ی بیشتری در زمینه ی کار با HTML و CSS در مقایسه با زبان برنامه نویسی در سمت کلاینت JavaScript دارند، طراحی این کتابخانه به گونه ای است که شروع به کار و یادگیری مفاهیم پایه ای آن برای تازه واردان (و همچنین افرادی که تجربه ی ناچیزی در زمینه ی برنامه نویسی دارند) آسان می باشد. این کتاب به سبب ثبات و انسجام در انتقال مفاهیم برای برنامه نویسان خبره نیز انتخاب مناسبی می باشد.

LearningjQuery - Fourth Edition در واقع نسخه ی ویراست و بروز آوری شده ی jQuery است. با مطالعه ی این کتاب آموزش های لازم برای افزودن قابلیت تعامل به صفحات و متحک سازی المان ها در آن ها را خواهد دید. حتی اگر تلاش های قبلی شما برای افزودن قابلیت های جدید با JavaScript خالص با شکست مواجه شده، این کتاب شما را در جهت رد موانع برنامه نویسی پیرامون AJAX، eventها، افکت ها و امکانات پیشرفته ی جاوا اسکریپت راهنمایی می کند.  

To build interesting, interactive sites, developers are turning to JavaScript libraries such as jQuery to automate common tasks and simplify complicated ones. Because many web developers have more experience with HTML and CSS than with JavaScript, the library's design lends itself to a quick start for designers with little programming experience. Experienced programmers will also be aided by its conceptual consistency.

LearningjQuery - Fourth Edition is revised and updated version of jQuery. You will learn the basics of jQuery for adding interactions and animations to your pages. Even if previous attempts at writing JavaScript have left you baffled, this book will guide you past the pitfalls associated with AJAX, events, effects, and advanced JavaScript language features.
